Specification of Letters Patent.

Patented March 23, 1909.

Application filed July 1'7, 1908. Serial No. 44= l,037.

To all whom t'tmay concern:

Be it known that I, TnoMAs SoHoLEs, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Cumulative Books, ofwhich the following is a specification.

This invention is intended particularly for use in the binding ofencyclopedias or other records of current events or information which itis desirable to supplement from time to time, by means of insertscontaining current news, records or information, in order that the bookmay be kept up to date without the necessity for publishing supplementsin the form of separate volumes, which are inconvenient for reference,wasteful of space, and disturb library arrangements.

The present invention relates particularly to the method of bindingtheoriginal volume in such manner that inserts can be added from time totime without in any manner distorting the shape or arrangement of theoriginal volume, and without rendering it more bulky or cumbersome.

Furthermore, the invention relates to they use of simple and easilymanipulated means for securing the inserts, so that the purchaser of thebook can readily make the inserts himself without difliculty and in aperfect manner, so that the book will not be disfigured when the insertsare made.

The invention consists inthe features of construction and combination ofinafter described and claimed. c

In the drawings, Figure 1 is a front elevation of a book laid open,showing the attaching device of the present invention; Fig. 2 a planview of the temporary leaf and permanent stub and the permanent fillingpiece; and Figs. 3 and 4: views of two styles of inserts intended foruse with thebook of the present invention. Y

The book, in its original form, as published, comprises a plurality ofordinary leaves 6 which are bound together in any suitable and wellknown manner. At suitable points where it is" desirable to apply insertsfrom time to time the book has bound thereinto permanent filling pieces7 which extend into the book a very short distance for purposes to behereinafter explained.

Adjacent to each of the filling pieces the book has bound thereinto aleaf 8 which comprises in part a permanent stub portion parts here- 9 ofa different width from the filling piece, so that one of saidadjacentparts will extend beyond the other to afford a pasting surface for thereception of the intended insert. The permanent stub portion of theleaf, in its original form, extends outwardly to a tearing line 10 whichis preferably, though not necessarily, formed in the paper by means ofperforations. A portion 11 of the leaf 8, outside of the tearing line,which may be termed the temporary leaf portion, is of a double thicknessof paper as compared with either the stub portion or the illing piece,the thickness of this temporary portion being substantiallyequal to thecombined thickness of the, stub portion and the filling piece.

The inserts may be of either of two forms, as shown in Figs. 3 and 4.Fig. 3 shows an insert having a body portion 12 of a double thickness ofpaper, which double thickness terminates short of the inner margin ofthe insert, leaving a pasting edge 13 of single thickness.

double thick temporary leaf 11, so that When the insert is a lied theoriginal thickness of the book wie maintained. Fig. 4 shows an insertwhich comprises two single leaves 14 and 15, the first of which is inthe form of a main leaf and the latter of which is in the form of a flyleaf pasted on the main leaf in position to bring its inner edge outsideof the margin of the main leaf, which arrangement provides a pastingedge 16 of single thickness similar to the pasting edge 13 of the insertfirst described.

In the form orignally published, the book, at the places prepared forinsertions, will be of uniform thickness from the back to the edge, inview of the fact thatthe stub and the filling piece are each of a singlethickness and together constitute a double thickness of paper, whichdouble thickness is main tained out to the edge of the book by thedouble thickness of the temporary leaf portion 11, so that the book willnot be distorted at any point. When it is desired to apply an insert,the temporary leaf portion 11 will be removed along the tearing line,leaving a. ermanent stub, which stub Will be of a dillerent width thanthe filling piece, one projecting beyond the other sufficiently toafford a pasting surface of single thickness adapted to receive thepasting edge of the insert, which is likewise of-single thickness.

The body portion of the insert is of substantially equal thickness withthe The thickness of the body ortion of the insert will equal thecombine thickness of the asted portions, so that every portion of thebook, from the back to the edge, will be of equal thickness when theinsertion has been made.

The thick portion of the leaf 8 will, in all cases, terminate outside ofthe edge of the filling piece, whatever the width of the latter may be,so that at no point will there be three thicknesses of pa )er of theparts intended to provide for the making of insertions. VJ here it isdesired to insert a single leaf affording two pages of reading matter itis preferred to use an insert of the style shown in 3; but where it isdesired to provide four pages of reading matter an insert of the styleshown in Fig. 4 can be used, which, of course, doubles the surfaceadapted .to receive printed matter. However, the insert of Fig. l can betransformed into the insert of Fig. .3, by merely cutting the insertalong the fold, the thickness of paper in each case being the same.

In the specification and claims, where the term temporary leaf is used,it will be understood that it is not intended by such words to limit theinvention to one in which such leaves are free from printed matter. Infact, the invention might be applied to books in which the removal ofprinted leaves and the substitution or possible substitution of otherleaves is contemplated.

Vrhat I regard as new and desire to secure by Letters Patent is:

1 A book having a narrow filling piece of a single thickness boundtherein at each point intended forthe reception of an insertion, andhaving adjacent to each filling piece a leaf provided with a tearingline near its inner edge, dividing the leaf into a'permanent stubportion-of a single thickness of pa -er having a width unequal to thatof the filing piece, and a temporary portion having a thickness of paperequal to the combined thickness of the filling piece and. the stubportion, said double thickness terminating outside of the outer edge ofthe filling piece, substantially as described.

2. A book having a narrow filling piece of a single thickness boundtherein ateach point intended for the reception of an insertion,

and having adjacent to each filling piece a leaf provided with a tearingline near its inner edge, dividing the leaf into a permanent stubportion of a single thickness of pa )er having a width greater than thatof the filling piece, and a temporary portion having a thickness ofpaper equal to the combined thickness of the filling piece and the stubportion, substantially as described.

3. A book having a narrow filling piece of a single thickness boundtherein at each point intended for the reception of an insertion, andhaving adjacent to each filling piece a leaf provided with a tearingline near its inner edge, dividing the leaf into a permanent stubportion of a single thickness of paper having a width unequal to that ofthe filling piece, and a temporary portion having a thickness of paperequal to the combined thickness of the filling piece and the stubportion, said double thickness termiimtiug outside of the outer edge ofthe filling piece, in combination with an insert having a body portionof a thickness equal to the combined thickness of the stub and thefilling piece, except at the edge intended. for attachment, said edgebeing of a single thickness of paper and equal to the thickness of thefilling piece, substantially as described.

4. A book having a narrow filling piece of a single thickness boundtherein at each point intended for the reception of an insertion,- andhaving ad acent .to each filling piece a leaf provided with a tearingline near its inner edge, dividing the leaf into a permanent stubportion of single thickness of paper having a width greater than that ofthe filling piece, and a temporary portion having a thickness of paperequal to the combined thickness of the filling piece and the stubportion, in combination with an insert having a body portion of athickness equal to the combined thickness of the stub and the fillingpiece, except at the edge intended for attachment, said edge being of asingle thickness of paper and equal to the thickness of the fillingpiece, substantially .as described.
